i'm planning my next build, and pretty on the line about the cranks i want. if i went with bmx cranks, i'd probably go with profiles; undecided when it comes to track.

now here are my concerns:
-fit. after reading up on them and searching the forum, i'm fairly certain they will work. (the frame will be, as of now, a soma rush.)
-weight. they're heavy, and i don't know if i wanna drop the extra cash for the lites. also, the lites would be 170 vs. the 165 of the regulars. how noticeable is the weight difference? i know the numbers (off the top of my head they're about twice as heavy as track cranks), but how does it affect riding?
-functionality. i think they look gorgeous on a fixed gear, but! i don't want to feel limited by them. of course, i could put the iros from my current bike on it, but that might be a pain in the ass. some early calculations place the bike at over $1000, which also makes me hesitant--spending big bucks on a bicycle that is potentially limiting in its use. (this goes back to the weight issue. will it become noticeable after 20, 30, 40 miles? more?) also: is there any chance of stripping the axle when skidding? i'd use a brake, but i find skidding quite fun (though i'm sure i don't do so extraordinarily much).

so that's that.

thank you in advance, y'all.
